Human factors (HFs) are increasingly acknowledged in workplace safety, yet their influence on preventive action remains uncertain. In high-risk sectors such as quarrying, it is essential to understand whether HF findings in accident investigations translate into effective corrective measures that support organisational learning and safety culture. The objective of this study was to assess the depth of human factor analysis in occupational accident investigation reports and to examine how this analysis influences the nature and target of proposed preventive actions. The study reviewed 150 accident investigation reports (2014-2024) from a multinational quarrying company, assessing HF recognition, depth of analysis, and the nature and target of proposed actions. HF were referenced in 90 reports; however, only 24% recommended preventive measures beyond individual-focused interventions. Most corrective actions centred on retraining, reminders, or procedural updates, while systemic or organisational contributors were rarely addressed. Reports demonstrating deeper, systemic HF analysis were rare. Findings indicate that recognising HF alone does not reliably drive systemic change. To improve safety outcomes, HF should be integrated not only into accident analysis but also into the development of preventive and corrective actions.
